The Invention relates to a computer-aided method for detecting and evaluating consumption data, in particular heat-, stream-, Gas-, water consumption, in the management of real estate, at respective measurement points of the building by means of consumption sensors are identified, wherein the consumption data quasi-continuously, in particular daily, determined and immediately be sent to a central or plotting station temporarily stored in predetermined or predeterminable time intervals and plotting station be sent to the central, wherein the quasi-continuously determined continuously accumulates [...] following the consumption data be, so that to each [...] an accumulated consumption value is present, and that all Consumption data or each accumulated consumption value during a predetermined period of time, in particular during a management period, saving, and that at any time during a predetermined period of time the accumulated consumption value on this Time with that of a previous period, in particular the preceding management period is compared.
